Dear all,
I start using SpeedMod since version K12K.
There is no problem when I update the kernel from K12K to K12L, K12M, K12P, until from K12P to K12Q and so on.
After flashing with Odin and reboot, the phone becomes very slow, both in operation and the touch screen response.
I have tried updating from K12P to K12Q, K12R and K12S, they have the same symptom and slow. When I flash back to K12L or K12P, it becomes normal.
Any advises please?
Thanks in advance.
My phone info:
ROM: Stock 2.2 FROYO.ZSJPE
Maybe you should wipe the dalvik cache and cache. Go to recovery mode - clockworkmod options - wipe dalvik cache. do the same with cache partition.
Then reboot. That first reboot will take longer than usual because the dalvik cache has to be rebuild again. After that everything should be fine.
Thanks for your reply.
I have tried wiping the cache, then the dalvik cache, but it seems remain the same --- slow and lag. I would like to know if there is any sequence, let's say wipe the cache first, then wipe the dalvik cache, then flash the phone? or something else?
After wiping the cache, in general speaking, how long do I have to wait after the reboot?
Thanks in advance.

What i mean is that the first reboot after wiping the dalvik cache takes longer than usual because the dalvik cache has to be rebuild again.
You might check in the task manager if there's any running process cunsuming cpu time, which could lead to laginess. There are many things that could produce lags (widgets,apps etc.) I dont know what's installed on your phone.

I see. However, I am thinking if the lag is because of the apps. Since I am using the same apps before and after the kernel update. I did wipe the dalvik cache after flash, but after reboot, the phone response very slow, and whenever I click the home button, it just did not show up.
Any more ideas? Thanks a lot.

What i would do in your case would be:
Backup all important data/apps etc.
Then do a complete wipe and reset to factory defaults.
Then flash the latest firmware: froyo 2.2.1
Then flash speedmod kernel and apply all recommended tweaks.
After that restore app by app and rethink the real use of each app (do you really need/use it?).
Might sound complicated but it might be even easier than loosing more time on hopeless attempts to solve the problem...

Cheers man, this will be my last step. Thank you for your help.

NP Tell us if you succeeded. You might want to try wiping thumbnail database before (forgot to mention that beforehands).
Sent from my hand
Just done a factory reset (erase data + data cache + dalvik cache)
and flash the new version of kernel. The phone is back to normal now.

So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

quick question, if you do a factory reset with odin and start from scratch, should you delete everything that is on your internal SD? Would that be a full complete wipe?
That is a FULL wipe but thats not what im talking about. Just the internal phone stuff.
what is formatted when you click to format /boot? for some reason I always thought that formatted the boot loader so I dared not touch that, but now I'm realizing how stupid it would be to even put that option there and how many more phones would have been bricked at this point. anyway when I install a new rom I pretty much wipe everything (including dalvik) except for /boot and /emmc ( I even formated the external recently but moved back images, efs backup, and avatar), then mount /sdcard, insert rom then flash, fix permissions.
formats the boot animation?
or after the VIBRANT logo
it's a ritual for me whenever i install a new rom to go through this installation method. I also notice that i tend to experience far less "bugs" then others.

Just being curious because some say it isn't cleared in the Factory Reset. Some ROM and kernel devs do suggest clearing Dalvik Cache after doing a Factory Reset because it prevents some apps giving FCs after flashing a new ROM.
Side note: I wipe dalvik about once every two weeks whether I am flashing or not. Helps with cleaning up corpses and getting better RAM usage. Thanks for the info Alan.
extra post :/
Nice find!
..now bend over.
One question Alan.
Can I Odin to stock from ICS passion just like we go from gingerbread or froyo from? Or is there a special way to get back to stock jfd? I want to try out jcc from but I don't know if I could just Odin to stock from passion. Thanks

What you using to reinstall apps and/or app data? Everytime I install a new ROM, I lose all my data connected to an app. For example, I play Drag Racing and you have to create a new login name everytime I install a new ROM. I would like to at least save the data related to that app.

Well, i am stuck at bootlooping after flashing CM7.1 onto my friend's device, we've tried many times flashing it with different ways, but it seems to get stuck everytime at the bootscreen, i know the initial boot can take up to something like half an hour but after 2,5 hours we gave up, downgraded to 2.3.4 again using odin, and tried again on a different way (different recovery)
this is how we flashed it:
-made sure we had 2.3.4
-wiped data and cache with CWM 4.0.0.idk (the odin package for this CWM was included in the thread)
-installed CM7, everything went smooth
-rebooted, and then it got stuck
I really want to get this to work for him, any help from you guys?
is it because i wiped after flashing ?
Well the process should be like this :
1. Wipe data - Wipe cache - Wipe Dalvik-cache - Wipe Battery stats
2. Flash ROM
3. Wipe data - Wipe cache - Wipe Dalvik-cache - Wipe Battery stats
So twice?
He's not here right now with the device, but i want to gather enough info for tomorrow to retry

Yeah, it is safe to wipe before and after flashing.
And you're sure you did wipe dalvik-cache right ?
errrrmm, i don't remember, i think i did tho, i will, as again, retry tomorrow with also wiping dalvik
Well, as for me, when something went wrong, i flashed my device back to stock froyo first.
Then flash GB, Flash CWM, clear data and cache, flash the rom, clear data and cache again.
Reboot.
That's it

Just go into recovery and wipe cache and dalvik cache and reboot and it will be fine

Hi guys!
As you can see in the title im a lil bit confused about full wipe and i got 1 question!
What's the process of a full wipe cuz i saw in alot of ROMs threads and im aware of not doing something stupid and bricking my phone,can somebody tell me what a full wipe includes?
Aswell i would like to know the steps for a full wipe before flashing a ROM!
Sorry for my bad english and thanks!
Full wipe means all data of previous rom you have installed to be wiped clean, all email accounts, contacts in the address book and apps will be deleted. That is why is always best to backup your apps with Titanium backup
All other things like on your sdcard still stays intact.
Full wipe steps:
1-Reboot into recovery mode ( To enter recovery mode, shut down your phone and wait for it to be completly turned off then you hold the Volume Up + Home + Power )
2-Do wipe data/factory reset.
3-Wipe cache.
4-Go advanced wipe delvik cache
